Application filed July 18, 1921. Serial No. 485,688.

To all whom it may concern:

Be it known that I, HENRY ScnUMAcHnR, a. citizen of the United States, residing in Buflalo, in the county of Erie and State of New York, have invented new and useful Improvements in Applicators, of which the following is a specification.

This invention relates to an a plicator which is more particularly designe for applying material, such as a medicated salve or powder to parts of the body of a person which are diflicult of access by the use of the persons own hands only and without the aid of another person, particularly the back of the body, which can only be reached ordinarily with difiiculty without the use of special means. .It is to be understood however, that this device can be used for other purposes, where it is desired to apply a material evenly and conveniently from a supply receptacle or reservoir to a surface intended to receive the material.

It is the object of this invention to provide a device of this character which will permit of appl ing to the surface to be treated various inds of materials either in a powder or in a semi-fluid condition and to discharge this material, if desired, under pressure to the face of the device whereby the same is rubbed or spread over a surface intended to receive the same and also to permit of regulatin the discharge of the material, as require A further object of this invention is to so construct a device of this character that the same can be readily filled with the material to be applied, which can .be thorou hly and easily cleaned and which is not on y convenient in use but ermits ordinarily inaccessible parts of the ody to be easily reached and applying material thereto.

In the accompanying drawings: Figure 1 is a longitudinal section of one form of applicator embodying my invention. Figure 2 is a top plan view of the same. Figures 3 and 4 are horizontal sections taken on the correspondingly numbered lines in Fig. 1 and looking in the dirliegtion-of the arrows associated with these Similar characters. of reference refer to like parts throughout the'several views. The receptacle or'reservoir intended. to contain a supply ofmaterial which is to be a plied to a surface of the body or elsew ere, may be variously constructed, but as shown in the drawin s the same comprises a tubular o'r'circular ody or wall 10 which is closed at its upper end by a tight upper head 11 while its lower end is closed by means of a removable head which is detach ably connected with the body 10.

As shown in Fig. 1, this lower head, in its preferred form, comprises a lower or outer disk 12 having an upwardly projecting marginal flange 13, so that the same is of downwardly dished form, and an annular rim 14 projecting laterally from the upper edge of the flange 13 and engaging with the lower edgeof the tubular body or wall 10. The lower head'is detachably connected with the body 10 by means of a clamping ring having a screw threaded rim17 which engages with the corresponding screw thread on the lower end of the body 10 and is provided at its lower end with an inwardly projecting flange 18 which engages against the underside of the rim 14 of the lower head. Above the outer or lower diskis arranged an upper disk 15 which is provided with a down,- wardly or outwardly projecting flange 16 at its margin and is arranged within the flange 13 of the lower disk and serves to space the lower disk 12 and the upper disk 15 apart so as to form a chamber between the same.

A plurality of bunches of bristles 19 extend at their upper ends through openings formed in the lower or outer disk 12 and are secured in place by means of a filling 20 of cement which is arranged within a chamber or space between the lower and upper disks 12, 15, and surrounds the upper ends of the bristles therein, so that these bristles are firmly secured to the lower head of'the receptacle andwill not become loose or detached when rubbing or brushing the outer ends of the bristles over the surface to which the treating material is applied. This treating material is conducted from the interior of the receptacle to the underside of the lower head at the base of the bristles. by means of a plurality of ducts, conduits, or

openings extending through thelower head.

These ducts are preferably constructediin place by upsetting or riveting the lower end of the nipple against'the underside of the lowerdisk 12 while its upper end is upset or riveted against the upper side of the upper disk 15.

l The flow or discharge of the material from the receptacle or reservoir through the dischargplnipples 21 to the base of the bristles may e regulated in accordance with the requirements, this being preferably effected by the" means which are shown 1n Figs. 1 and 3 of the drawings and which comprise .a rotatable shutter 25 of disk form which is,

ivoted upon the inner side of the lower liead of the receptacle and provided with an annular row of o enings 27 which are adapted to be move into or out of registration with the assages of the nipples 21 for a the purpose 0 either fully uncovering'these outlet assages, or fully covering the same, as we as permitting of particularly uncovering these nipplesso as to regulate the amount of material which can escape from the rece tacle as desired. This shutter is preferably provided with a finger piece 26 at one edge thereof, whereby the same may be turned to adjust the position ofthe shutter or valve when the lower head of the race tacle is removed from the body.

The preferred means for pivotally con- "necting this shutter with the lower head from this receptacle to the bristles of the brush this material may be spread evenly over the surface to be treated and also rubbed into the surface for curative purposes, as for instance when applying salve or medicine to an affected part of the body. The discharge of this material, particularly when the same is in the form of a powder or a ,salve, is preferably accomplished as often as required by means of pressure applied to the same within the receptacle.

- Any approved means may be employed for efiectingthis pressure, for example, as shown 1n Fig. 1, this may be accomplished by means of a tube 22 of flexible rubber or other suitable material, having its outer end connected with the upper part of the reservoir and an air forcing or compressing device such as a bulb 23 connected with the tube 22. By pressing on this bulb, which is constructed with a valve mechanism similar to that commonly employed in connection with atomizers and similar spraying devices, an air pressure is produced upon body, said head havin asses the material within the receptacle which 24 of-sufiicient length is rovided, which is connected at its front en with-the body of the reservoir or other part thereof, while its rear end is adapted to be grasped by the hand of the operator and thus ermit of reaching the arts which ordinari y areinaccessible or ifiicult of access.

The receptacle may be readily filled with a new suppl or charge of material by removing the ower head from the body, and while thus removed the arts may also be thoroughly cleanedand dlsinfected and thus enable the same instrument, if desired, to be used either with different medicines or preparations and also used on different persons in accordance with the treatment and the character of the medicines or other materials which are to be applied to the respective persons.

I claim as my invention:

1. An applicator having a receptacle adapted to receive the material to be applied and comprising a tubular body and a head arranged at the front end of said body, said head having outer and inner disks which are spaced apart, ducts extending through said disks, bristles extending through said outer disk into the space between the same and the inner disk, and a filling of cement arranged between said disks and securing the mner end of the bristles therein.
